4.4.1 (2026-06-15)

4.4.1 + Nomads DLC release notes

Nomads Release Notes

• Nomadic Empires introduced
  • Arkships
    • Massive mobile capitals that replace homeworlds entirely. Serve as colonies, shipyards, and warships simultaneously, with three specialization classes (Military, Scientific, Civilian) that can be upgraded through three tiers and customized with modules, systems, and late-game Spinal Mounts. 
  • Waylines & Waystations
    • Construct Waystations to harvest resources from systems without claiming them. Adjacent Waystations automatically link into Waylines that propagate trade and modifier bonuses. Wayline Pacts allow two Nomadic empires to share each other's network benefits. 
  • Contracts
    • Settled empires can issue task-driven Contracts (Military, Science, Resource, Diplomacy) for Nomadic empires to fulfill. Completing Contracts earns Trade, improves Opinion and Trust, and unlocks deeper diplomatic options including Wayline Pacts. 
  • Settling and Embarking
    • After completing the Adaptability or Versatility tradition, Nomadic empires can Settle on an empty planet, with options to settle partially or fully and leave the remainder as a subject. Settled empires can Embark onto Arkships through a mirrored process, converting their starbases into Waystations. 
• New Ambition path: Defender of the Galaxy
  • Transforms the Defender of the Galaxy Ascension Perk into a full five-level Ambition path. Progress by cooperating with other empires, assuming Galactic Custodianship, and forming the Galactic Defense Force. Unlocks the Paladin Initiative and unique hero ships commanded by promoted admirals. Win condition: defeat two end-game Crises and abdicate your Custodianship. 
• Stellar Cannon Megastructure
  • A purely offensive Megastructure requiring a neutron star or pulsar, buildable without an Ascension Perk. Fires your entire energy stockpile at a target system after a 140-day charge, dealing ship damage and colony devastation (10%/25%/50% at each tier). Shots over 50,000 energy also shift all planets in the system one step up the dryness scale. 
• Nomadic Enclave: Champions Forge Live!
  • A roving gladiatorial enclave that hosts fleet combat tournaments every twenty years across the galaxy, with weight classes scaling from early- to late-game fleet sizes. Winners hold the Trophy relic until the next tournament. Also offers services including combat intelligence on rivals, tournament venue selection, and introductions to Nomadic Paragons. 
• New Nomadic Origins
  • Voidfarers
    • The general-purpose Nomadic origin. Provides a flexible, unscripted start with no overriding narrative obligation, suited to players who want to define their own nomadic path from the ground up.
  • Heirs of the Khan
    • Begin as survivors of a Khan's assassination, hunted by escalating Marauder bounty fleets. Complete unique military Contracts to weaken your hunters. Survive and potentially claim the throne yourself! 
  • The Sacred Path
    • A Spiritualist origin built around surveying a series of sacred sites scattered across the galaxy by your ancestors. Each site presents a distinct choice about faith and history. 
  • Forever Cruise
    • Two species share a single Arkship: a working Crew and a leisure-seeking Passenger class. Balance the Passenger Satisfaction situation to avoid Planetfall on one extreme and Mutiny on the other.
  • We’ve also added a special “Hospitality Servitors” variant of the Rogue Servitors civic, where the Passengers are even more demanding and maintaining the cruise is more difficult.
• New Paragons
  • Orun Veyth, the Revenant
    • A scarred admiral who lost everything to a purge and has been settling the debt ever since. 
  • Ashar, the Wandering Sage
    • She held a seat at a royal court for decades, then walked away from it because the stars had more to teach her. 
  • Sero the Younger, the Naturalist
    • He left a prestigious Grand Archive to study living things instead of dead ones.
  • Unit Solace, the Caregiver
    • A synthetic father who chose exile over abandoning his fragile son when his people synthetically ascended.
  • Th'aal Hask'Guron, the Champion
    • A warrior of considerable size and considerable joy, who treats every battlefield like a hunting ground and your Arkship like a trophy hall. 
  • Seralune, the Lost Princess
    • She boards your Arkship with nothing but polite manners and the feeling she has been somewhere before. Follow where she points.
• New Nomad Civics
  • Caravan Masters
    • Every Waystation is a marketplace, every contract a relationship, and every relationship a potential profit margin. 
  • Void Reavers
    • Not all who wander are lost, some are just waiting for you to let your guard down. Siphon resources from colonies in systems where your Waystations lurk, or skip the subtlety and plunder planets directly with the Plundering bombardment stance. Yarr!
  • Star Seekers
    • Life between destinations is its own destination. Gather resources as you travel, then burn through your stockpiles in a galaxy-spanning festival that grounds one Arkship and celebrates everything your people have seen.
  • Flight Schools
    • The best pilots in the galaxy didn't grow up with a planet to land on.
  • Deep Sleep
    • Not every passenger needs to be awake for the journey. Manage your population through the long transits between stars, keeping only the hands you need on deck.
• New Species Traits
  • Photoadaptive/Solar Celled
  • Recursive Learners/Structural Awareness
  • Reaver
    • Grants Commanders the Plunderer trait
  • Terraphobic
  • Interconnected
• New Music tracks by Andreas Waldetoft and Batzorig Vaanchig
• 8 new achievements 

4.4.0 ‘Pegasus’ Patch Notes

Feature

• The Paradox Launcher now automatically disables your mods on major version updates.
  • To re-enable your mods after they have been updated for the patch, change the ‘DLC only’ play list back to your associated mod list. Your preferred mod list will then stick through the major version.
  • Attempting to resume an incompatible save will now divert you to the main menu instead of loading it.
  • The launcher should now show a warning if there has been a major patch since your last saved game
• Joining & Leaving wars in progress
  • Empires that are not the primary participant in a war may now attempt to  enter an ongoing war by negotiating with the leader of the side they want to join, or leave an ongoing war by negotiating with the leader of the opposition. These can be found as terms in trade negotiations.
    • Leaving a war creates a truce, and negatively affects your former ally’s opinion of your empire due to your treachery.
    • An opponent may be reluctant to let you get off easily if they feel that they’re winning the war, or if they particularly dislike you.
• Empires whose colonies are all occupied now suffer escalating consequences. Each month while fully occupied, they gain a stacking Hopeless War modifier worth +5% War Exhaustion gain, and their wars accumulate +1% Attrition per month, which can take them past the normal 100% cap. Both effects vanish the moment any colony is liberated. AI secondary participants with all colonies occupied also gain increasing desire to seek a separate peace.
  • This will generally only be relevant when an empire has allies in a war, or is in multiple wars with split occupation.
• To further celebrate our 10th Anniversary: We have added a background selector to the Graphics settings screen, allowing players to choose which animated main menu background is displayed, including all DLC frontends, Latest Release, and Random options.

Improvement

• Automated jobs now have their own workforce limit slider, letting you directly cap how many of a job's slots are filled by automation.
• Finished the removal of Unemployment begun with 4.3.0.
  • When a pop loses their job, they now immediately fall to their stratum's fallback category (Citizen, Maintenance Drone, etc.) rather than passing through a temporary unemployed tier.
• Reworked Nascent Stage pops to work more similarly to sub-species integration, with approximately 1/60th of the pops growing into their base species each month (on colonies that are at least 60 months old). This should result in Nascent Stage being more reliable and less error-prone.
• Improved how pops compete for jobs combining basic job weights and how efficient they actually are at them, so a more suitable pop will now properly displace one already holding a position. (i.e. Slaves and shackled robots will tend to displace free organics from worker tier jobs, intelligent pops will take more research positions, etc.)
• Higher-stratum jobs turn over more slowly - Workers and Simple Drones may reshuffle every 3 months, Specialists and Complex Drones every 7, and Elites every 13 - so an out-of-place pop won't be kicked out immediately but will eventually be displaced by a better fit.
• Gestalt pops have a weaker attachment to their current jobs overall.
• On underpopulated planets, pops tend to fill jobs proportionally between all the capped jobs they are eligible for, though bonuses to job efficiency (such as from the colony designation or traits) could heavily skew this towards certain jobs. They will still tend to prefer higher stratum jobs when possible.
• Prioritized jobs ignore this proportional fill, but lower strata jobs may still be bypassed in favor of higher weight ones.
• Pops should no longer take deficits into account for job prioritization, as this caused extremely erratic monthly behavior on underpopulated planets.
• Event option tooltips for ethic drift effects in the Costume Culture, Roots Reclaimed, and Fans No More First Contact events, and the Broken Shackles origin homecoming option, now show a single summary line instead of one entry per affected pop group.
• The System Initialiser selector now hides systems you are not eligible for (for example, KotG Sol if you do not have the KotG origin).
• You can now use Tab and Ctrl-Tab on the Starbase tab to advance to the next or previous owned Starbase. (This advances through upgraded Starbases, skipping Outposts.)
• It is now possible to queue the return order. Useful when issuing commands for the logistic ship and then you want it to return to the arkship to drop off the stockpile.
• Added a slider to set the amount of randomized nomadic empires that is spawned during galaxy generation.
• When building megastructures that are meant to be located outside of the gravity well, the eligible space will be highlighted in green instead instead of marking ineligible space in red.
• the kill_country console command now accepts an optional ID parameter
• Choosing a Megastructure from the fleet order button moves the camera to the constructor's system
• Habitats and Ringworlds now explicitly state that they have artificial climates.
• Colonize button on planets will now be disabled ( with a tooltip explaining the reason ) if there is already a scheduled colonization action for that planet. Previously players would still get blocked, but it took more steps to realize that you have already ordered a colonization ship.
• Added message for mission completion.
• Orders to construct megastructures will no longer be automatically canceled by issuing some other order. Player will need to explicitly click cancel orders button to avoid unintended cancellation and loss of progress.
• Fleets are now willing to fight further from the center of the system. Especially noticeable if fighting stationary targets at the edge of the system.
• Fleets that return to or are built at a Juggernaut or Arkship now automatically follow it.
• The Megastructures UI now shows the top 10 recommended systems for Arc Furnaces, Dyson Swarms, and Habitats when hovering over each megastructure type.

• Make selectables of different types not able to be selected together

• Unity resource culling conversion value adjusted from 1 to 3
• Commander traits that grant resources when ships are killed (Material Liberator, Crusader, Shipbreaker, Plunderer) now have larger rewards and scale by the destroyed ship's used naval capacity instead of a flat per-kill amount.

UI

• Situation Log UI improvements, including categorization of entries and new interface looks
• Starbase module and building tooltips now show equipped component stats
• Ship details panel now shows full weapon and strike craft stats in component slot tooltips
• Expansion planner sort buttons now display district type names instead of resource names.
• Fixed too large leader tooltip hitbox in Paragon recruitment and conversation event windows.
• Build queue tooltips for Shipyards now show ship class icon and design name
• Megastructure UI overhaul and art pass
• Fixed misleading tooltip for outpost influence cost when it is capped.
• Hid leaders from Combat UI
• The Planet View UI now shows districts that are being built as part of the overview where the built, unused and blocker ones are to give a more accurate overview of the situation
• Inactive triggered Auras will now be hidden from the component tooltip of the shipview
• Rename and move some steps in the Empire Creation menu
• Add a scrollbar to Empire Creator's planet class description
• Transport fleets docked at a starbase without a docked ship upkeep modifier no longer show a "Ready to land troops" tooltip.
• "Research Projects in System" in right-click menu for construction ships is now shown if multiple construction ships are selected.
• Renamed "Civilian Ships" to "Utility Ships"
• Policy groups that have been unlocked but not yet initialized are no longer shown in the policies view.
• Tooltips can now update their text while locked in position.
• Removed the "Auto Track Log Entries" button from the event window (mods may re-enable it).
• Improved concept tooltips for starbase building and module unlocks.

AI​

• AI now treats unity as a real production target across all three plan stages, research can scale 40% higher in advanced (2500 -> 3500 cap), and endgame alloys drop from a 2300 ceiling to 1300 so that the trillions-of-research endgame research numbers can actually outcompete alloys for build slots/pops.
• The AI now steers building construction toward building sets that match each planet's designation for tighter, better-specialized worlds.
• The "underdeveloped planet limit" that was supposed to prevent AI overextension is more effective. Instead of only applying in the first 15 years and then only against bad planets, it now softly discourages colonization of any world once the empire already has too many undeveloped colonies.
• Empires that are still small will now expand more aggressively, so they more reliably claim their homeworld's guaranteed habitables and nearby good worlds before settling into build-up mode.
• AI resettlement now moves pops from overpopulated worlds to underpopulated ones regardless of how those planets got that way, rather than only emptying out worlds with terrible habitability. New colonies should grow faster and veteran worlds should stagnate less.
• On well-developed planets (2500+ pops), the AI is now more likely to round out its rural districts so it unlocks the building slots they provide. It still won't waste slots on a district whose specialization zones aren't available yet, so early-game behavior is unchanged.
• Fixed an issue where optional subplans (like pop count and strategic resource targets) were still required to complete a plan, which stalled the AI on one economic tier for long periods; they now behave as true stretch goals
• Added a new intermediate economic plan between the basic and advanced tiers, so AI empires experience a smaller jump in expected income (energy, minerals, alloys, research, etc.) as they graduate out of the early game.
• Fixed a bug where the AI's consumer goods scaling production check looked at the food stockpile instead of the consumer goods stockpile, sometimes causing the AI to over-build or under-build CG production.
• The AI now proactively tears down and rebuilds urban zones that don't match a planet's designation - for example, a col_foundry world will swap out a generic zone_industrial for zone_foundry to double-specialize into its designation. Swaps apply a per-building penalty for each existing building that doesn't carry over through the new zone's included_building_sets, require a larger affinity margin when the slot is already specialized to prevent churn between near-equivalent candidates, and must clear a minimum-benefit floor so the construction cost is justified by the economic delta. Planets already rich in matched buildings stay put; planets with mismatched buildings restructure.
• Colony designation affinity (the ai_building_set_affinity on colony types) now biases AI zone selection in addition to building selection. A designation that prefers the "foundry" building set will now also weight foundry-themed zones more heavily during construction planning.
• Nanotech Worlds: Fixed AI empires getting stuck after converting planets to Nanotech Worlds. The AI now prioritizes nanolabs, nanotech cauldrons, and nanite transmuters on pc_nanotech colonies instead of leaving rural districts unspecialized.
• The AI will now reactively build storage boosting buildings when any tangible resource is above 90% capacity.
• Increased AI weights for taking Ascension Paths. Added Spiritualist and Materialist AI weight synergies for Psionic and Cybernetic Ascension.
• AI empires that have taken the Synthetic Evolution AP will now always be able to take tech_synthetic_workers (even if they don't normally use robots).
• AI empires are much more likely to take Ascension Perks and their associated Tradition Trees.
• The AI now sometimes uses buildings that provide a static number of jobs, like Alloy Foundries or Civilian Industries.
• The AI no longer rigs their Hydroponic Farms with explosives, ready to blow in the off chance that their economy starts doing too well.
• Reduced the fleet power upgrade threshold the AI requires before they will upgrade ships from +30% to +10%.
• AI will no longer want to build army types that fail the "allow" trigger on all colonies.
• AI can now build armies that cost resources other than minerals or food.

Stability

• Fixed OOS with merging species (playing with nascent species)
• Fixed OOS with country economy due to dependency missing in threaded code.
• link_to effect now supports null bypasses (as both the scope and target) instead of crashing.
• Fixed a crash when closing the game via Alt+F4 or the window close button while a save was in progress.
• Fixed a crash that could occur when hovering over event option tooltips generated by effects iterating large numbers of pop groups.
• Fixed an OOS happening on hotjoin when a situation has enough progress to go past the last stage.
• Fixed a crash that could occur when AI empires evaluated megastructure construction orders.
• CS_SPECIES_COUNT, CS_SPECIES_INDEX OOS when playing with nascent species
• CS_COUNTRY_RESOURCES OOS
• Fixed crash when using horizontalScrollbar in containerWindowType.
• Fixed crash on Mac in galaxy generation due to running out of stack when randomizing traits for species

Modding

• Added is_nomadic option for create_country.
• Added "rat" as an alias for research_all_technologies console command, which now works in addition to "rta".
• The demotion and promotion blocks in pop job script definitions have been removed.
• The intermediate unemployment job types and pop categories (ruler_unemployment, specialist_unemployment, worker_unemployment, complex_drone_unemployment, simple_drone_unemployment, slave_unemployment2) have been removed.
• The pop_unemployment_demotion_time_mult static modifier and pop_cat_X_unemployment_political_power family of modifiers (used in living standard definitions) have been removed.
• Nascent Stage presapient maturation is no longer handled via script demotion chains. It is now driven by the new forced_integration block on species traits. Set integration_rate (fraction of pops converted per month) and optionally minimum_colony_age (in months) on any species trait to gradually integrate pops into their parent species.
• Two new defines: AI_UNBUILT_DISTRICT_BOOST_POP_THRESHOLD (default 2500) and AI_UNBUILT_DISTRICT_BOOST_MULTIPLIER (default 2.0). The multiplier is applied to any districts that have 0 built when the planet meets the pop threshold, lacks that district type, and at least one of its specialization slots has a potential district specialization for the planet.
• A new ai_building_set_affinity = { = ... } block is now accepted on colony types - each entry multiplies the AI's build weight for buildings in the named building set when that designation is active.
• Defines AI_RESETTLE_FROM_LOW_HABITABILITY_THRESHOLD and AI_RESETTLE_TO_HIGH_HABITABILITY_THRESHOLD have been removed - they no longer drive behavior. The AI now only requires source pops ≥ 2× target pops, and rejects any target with habitability below AI_MIN_HABITABILITY_TO_COLONIZE.
• Two new defines in common/defines/00_defines.txt: AI_FEW_PLANETS_COLONIZATION_THRESHOLD (default 5) and AI_FEW_PLANETS_COLONIZATION_BOOST (default 0.25). When owned planets < threshold, colonization weight is multiplied by 1 + (threshold - owned) * boost.
• UNDERDEVELOPED_PLANET_LIMIT is now a soft weight penalty (limit / count multiplier) applied inside ColonizePlanets rather than a binary rejection in ShouldColonizePlanet, and no longer gated behind AI_BUDGETING_*_YEARS.
• The "optional" flag on an economic plan subplan now truly exempts it from plan fulfillment. Previously it only controlled the order in which the subplan was factored into the scaling-subplan loop, but the subplan's income/pops/naval_cap still counted toward graduation targets. If your mod relied on the old behavior to force pop or strategic-resource gates, change those subplans from optional = yes to omit the flag entirely, or add an equivalent requirement via a new non-optional subplan.
• New define AI_ZONE_SPECIALIZATION_AFFINITY_DELTA (default 0.5) in common/defines/00_defines.txt. This is the minimum affinity improvement a candidate zone must offer over the existing district specialization before the AI will propose a swap. Raising it makes the AI more reluctant to restructure existing zones; lowering it makes the AI more aggressive about perfecting specialization.
• Colony type ai_building_set_affinity entries now also apply to district specialization types. Any district specialization whose included_building_sets list includes a building set named in the colony's affinity table will receive the corresponding AI weight multiplier.
• Added the -logempirestats command-line flag. When set, Stellaris writes one TSV row per (month, empire) to logs/empire_stats_.tsv with columns Game Date, Empire, Plan, Economy, Military, Tech. Covers every playable empire (including the player) for the full session; dead empires keep a row per tick with blank metric cells.
• Added a resource_stockpile_percent = { resource = value >= } trigger. Only valid for resources that have caps.
• New define AI_ZONE_SWAP_BUILDING_LOSS_PENALTY (default 0.2) in common/defines/00_defines.txt. Each existing building in the slot that can't be carried over via included_building_sets subtracts this much from the candidate zone's effective affinity. With the 0.2 affinity delta default, a 1.5 -> 2.0 swap tolerates up to 2 displaced buildings but refuses at 3 or more. Raise to protect developed planets; lower to let the AI restructure more aggressively.
• New define AI_ZONE_SWAP_RATCHET_MULT (default 1.5) in common/defines/00_defines.txt. Multiplier applied to AI_ZONE_SPECIALIZATION_AFFINITY_DELTA when the slot is already occupied by a specialized zone (affinity > 1.0). First-time swaps from a baseline 1.0 zone use the normal delta; swaps that would displace an already-specialized zone need a larger margin. Prevents ratcheting between near-equivalent specialized candidates.
• New define AI_ZONE_SWAP_MIN_BUILD_WEIGHT (default 2.0) in common/defines/00_defines.txt. Minimum CalcBuildWeight a zone-swap proposal must reach before it's queued - any swap whose economic delta doesn't clear this floor is discarded even if the affinity delta would otherwise allow it. Prevents slot churn where multiple candidates cluster near the top and the AI keeps swapping for marginal improvements.
• Added `bottomless` flag for resource converters.
• Added `pop_group_can_join_factions` game rule. Pop groups are no longer hard coded to have happiness to join factions.
• The -incrementalsaves command line parameter will now save every 25 years instead of skipping some. This frequency can be changed by the INCREMENTAL_SAVE_FREQUENCY define.
• Added completion_message_type, completion_message_localization, and completion_message_days fields to scripted actions. When set, the engine automatically sends a notification to the acting player on action completion, with FLEET/MEGASTRUCTURE and TARGET_PLANET/TARGET_SYSTEM/TARGET_FLEET variables pre-populated.
• save_global_event_target_as supports exhibits.
• save_global_event_target_as logs an error if used in invalid scope.
• New on_leaving_system_fleet on_action that gets triggered when a fleet is leaving the system.
• no more errors in the error log about invalid scope when "any\_" or "count\_" triggers finds no matching elements. It used to evaluate the nested triggers using the parent scope and now it uses an empty version of the correct child object.
• Added error logging if failed to randomly place a system with minimum distance from other systems or if the minimum distance is 0.
• Added error logging to move_system corresponding to the logging in spawn_system.
• Added show_in_build_menu = yes|no (default yes) for megastructure types. When set to no, the megastructure is excluded from the Build Megastructure picker dialog and suppresses the picker button entirely if no other megastructures are available.
• Orbital deposit spawn eligibility unified under canonical can_have_* scripted triggers.
• Added force_show_diplomacy and force_show_espionage, letting you forcefully display a scoped country's respective tab through script.
• New `create_random_fleet` effect with weighted ship designs and optional min/max per entry; the previous deterministic effect of the same name has been renamed to `create_balanced_fleet`.
• Tradition Swaps now support "unlocks_agenda" as an optional field. If you don't have one entered, it will use the one from the base tradition (if any).
• Updated GetPlanetMoon to work for Habitats, Ringworlds, and Arkships
• Renamed system_colony script lists to system_planet_colony.
• Added `level_tooltip` to Starbase Levels, this displays as a custom tooltip appended to the Upgrade/Downgrade starbase tooltips.
• Added `is_orbital_ring = yes|no` to ship sizes, this determines if the Starbase Upgrade/Downgrade button title displays "Starbase" or "Orbital Ring"
• Added `show_in_outliner` parameter to situation type
• Fixed "calc = pop_happiness" in scaled_modifier not working.
• `num_claims_on_system = { target = FROM count >= 6 }
• Introduced a new define SYSTEM_BUILD_AREA_COLOR to control what color should be used to highlight eligible space when picking a spot to build certain megastructures.
• Add has_contract and has_contract_of_type triggers
• A fleet scripted action with planet scope and cooldown 0 will now be ordered for the whole system when used from galaxy map
• Replaced defines BRANCH_OFFICE_COST_INCREASE_MIN_RANGE and BRANCH_OFFICE_COST_INCREASE_SCALE with BRANCH_OFFICE_INFLUENCE_COST_BASE, BRANCH_OFFICE_INFLUENCE_COST_INCREASE_SCALE and BRANCH_OFFICE_INFLUENCE_MAX_COST.
• Added country_branch_office_influence_cost_mult modifier.
• Add carries_colony requirement to special projects
• new carrier_is_type trigger
• Add script list effects and triggers for owned_mission and issued_mission
• Add issuer event targets from mission scope
• inherits_capped_modifiers_from has been removed from the game. It is replaced by shared_capacity_modifier which is now a pool that all districts on the planet share their capacity from. Allowing for new modding possibilities
• Add show_in_issue_list parameter to mission category
• has_cloaking_detection works on starbase scope now
• Add click_to_act_key field to scripted actions, displayed when they are clickable. If not written, a generic click text will try to get generated, based on scope
• Add has_mission_flag trigger to mission scope
• Add is_contract_type trigger to mission scope
• Allow add_mission_counter to be used directly in a mission scope
• Added on_megastructure_build_start on action.
• Trigger has_cloaking_detection now takes modifiers into account
• Megastructures can't have build and dismantle times \<= 0
• Add ship_size_damage_factor modifier
• Add triggered_requirement field to special projects
• Add is_nomadic government restriction
• Add is_nomadic country trigger
• Allow ship and fleet scope in set_graphical_culture effect
• Hooked on_actions for encampment and packing up from code
• Replaced is_moving trigger by is_system_locked
• New on_action on_system_locked_ship_killed fired when an encamped ship is killed
• Add can_access_decisions rule to show or hide the Decisions button
• Add time_to_accept and time_to_complete to missions
• Added custom_class_text_color as a hero ship parameter to determine which color highlight to use for the ship class on the fleet UI.
• Add create_sector effect for orphan colonies
• Added planet_artificial_max_districts_add which increases the district cap on colonies for which the planet class has is_artificial_planet = yes
• Add galaxy_radius trigger
• Removed on_fail effect for missions, on_cancel effect is now run when a mission is ended early, no matter the reason.
• `damage_ship` now supports passing the attacker country
• Added steal_planet_output effect
• Added potential trigger for situation types
• Planet decisions now support `important=yes` setting. Important decisions will appear at the top of the list and be be highlighted.
• Replaced has_authority = auth_corporate with is_megacorp = yes
• Deposits' potential, resources, and drop_weight now support astral rift scope.
• Updated deposits documentation.
• Replaced right_horizontal_slider with bottom_horizontal_slider, which correctly uses a horizontal button.
• Starbase scope now supports "ship" to scope to the station ship.
• scripted actions now support more on_actions along their process
• Updated `potential` and `possible` triggers for megastructures to include the constructing fleet or upgrading megastructure as a scope.
• Created a resource converters database used to handle stockpile alternate paying methods for a country
• Created `set_resource_converter` effect to set a country's resource converter
• Added construction_capabilities to ship size.
• Added error logging for unsupported values of "station" in deposit types.
• Removed obsolete game rule can_build_military_station_around.
• Megastructure definitions now support three new optional fields: tooltip_best_systems_header (loc key for the section header), tooltip_system_score (used to rank systems), and tooltip_system_filter (trigger block to exclude ineligible systems). Set tooltip_show_star_resources = yes instead of tooltip_system_score to display the star's actual resource output as the ranking metric. The number of systems shown is controlled by the MEGASTRUCTURE_TOOLTIP_BEST_SYSTEMS_COUNT define (default 10).
• Added the `override_trade_restriction` resource-converter flag. When set to `yes` on a resource in a country's resource converter, that country can buy and sell the resource on the market regardless of income or galactic market access (the income/galactic-market gate is skipped, but `tradable_in_market` is still respected).
• Ethics now support `triggered_country_modifier` blocks for conditionally applied country modifiers.
• New weapon_component_template fields collateral_damage and collateral_range for AoE damage to nearby hostile ships on hit, inheriting the weapon's penetration and damage type modifiers.
• New weapon_component_template fields chain_damage, chain_range and chain_count for arc/bouncing damage that randomly selects a hostile ship within range of each previous bounce target.
• New attacker_ship parameter on the damage_ship scripted effect for full on-action scope attribution when the damage source is a known ship.

Known Issues

• The galaxy is vast and full of riches. Space based deposits are more common than intended (almost every object in the galaxy has something on it!) but it’s pretty cool so this is probably going to turn into a galaxy generation slider.
• Occasionally Waystations with Cloaking devices suddenly believe themselves to be unable to cloak. Saving and reloading the game or upgrading the Waystation seems to fix this issue when it occurs.
• “The Eternal Chorus” nomad contract automatically cancels itself when taken.
• If you are at war and have Evasive civilian ships following your Arkship, and you enter a system with hostile enemies, the Arkship will stop and wait (forever) for the civilian ships that are too cowardly to enter the system to follow it in.
• The modifier name for effects from Operational Reserves doesn’t show up correctly in some tooltips, so your Workforce may show unnamed bonuses like “+20%”
• Some Shroud Accords or Auras grant benefits to planets or defense platforms - these are not useful to Nomadic Empires and should change.
• Some combinations of ethics in the Forever Cruise can leave you starting the game with extreme deficits (as your crew go to work jobs from the ethics-based buildings instead of worker tier jobs), and we plan on making some adjustments to the situation speed. (Currently we feel that it is progressing to the extremes too quickly.)

4.3.7 (2026-05-11)

4.3.7 ‘Cetus’ Release Notes

Modding

• The DLC ownership check has been made backward compatible for any mod that still includes them.

---

4.3.6 (2026-05-11)

4.3.6 ‘Cetus’ Release Notes

Feature

• The Utopia, Synthetic Dawn, Humanoids Species Pack, and most elements of the Galaxy Edition Upgrade have been rolled into the base game.
  • Utopia contains:
    • Megastructures, Habitats, Ascension Perks, Indoctrination, Advanced Slavery, Hive Mind empires, Fanatic Purifiers, and more.
  • Synthetic Dawn contains:
    • Machine Intelligence empires, Machine Rebellions, Machine Fallen Empire, 7 machine portraits, and more.
  • Humanoids contains:
    • 10 humanoid portraits, the Master Artificers, Pleasure Seekers, and Pompous Purists civics, the Clone Army origin, the humanoid shipset, and more.
• A Behemothkin portrait has been added to Reptilians if you are logged in with a Paradox Account.
• Added a Portrait Substitution option in Accessibility settings. 
  • When Arachnophobia Mode is enabled, spider-like portraits are replaced with alternative artwork on your client only, with no effect on other players in multiplayer. 
  • Arachnophilia Mode does the opposite, replacing non-spiders with spider-like portraits.

Bugfix

• Leaders can no longer become too old to die.
• Corrected Vipra the Vapor’s greeting audio

Performance

• Players with systems capable of exceptionally high framerates can now override the default 90 FPS render cycle cap by adding refreshCap=144 (or other values) to their settings.txt. The first time you launch Stellaris after this change, it will add refreshCap=90 if it's not present. The refresh rate will still floor at 30 and cap at your monitor's refresh rate. Note that increasing this value will leave less time for the simulation loop in favor of the rendering loop, and thus may negatively affect overall performance.

Stability

• Fix to a CS_SPECIES_COUNT, CS_SPECIES_INDEX OOS when playing with nascent species
• Fix to a CS_COUNTRY_RESOURCES OOS

Modding

• We've simplified how "very old age" is handled in code - the define is now a fixed point that makes you more likely to die if you are over 120% of your species' lifespan. As we've changed this from 100 to 1.2, you'll want to update any mods that changed this value.
• The Portrait Substitutions spinner in Accessibility will load all files in the game\gfx\portraits\portraits\substitutions folder when the game starts and add them to the spinner options. See the Arachnophobia and Arachnophilia options we have provided for the process to add your own Portrait Substitutions. 

---

4.3.5 (2026-04-29)

4.3.5 ‘Cetus’ Release Notes

Feature

• Added Stellaris: Season 10 Unlock Portrait: Vipra the Vapor. It can be found under Necroids if you purchase Stellaris: Season 10.

Improvement

• Added a new feature to the Seddom system.

Bugfix

• MSI no longer start with buildings they can't pay the upkeep for. 
• "Offworld Prospectors" jobs (Galvanic Synthesis civic) do not produce negative alloys anymore while the "Centrifugal Siphoning" edict is active 
• Cybernetic governors in Machine empires now correctly boost Pop Assembly rate rather than workforce efficiency.
• Robotic leaders in Driven Assimilator empires no longer lose the Cyborg trait after being modified.
• Driven Assimilators who complete the Cybernetics tradition tree unusually quickly no longer permanently miss the "Advanced Assimilators" government choice event.
• Volcanic World districts no longer disappear when terraforming to a Machine World or Hive World.
• Machine Worlds can now be assigned a Trade Colony designation for individual Machine empires, and colony automation correctly handles trade districts and specializations on such worlds.
• The Virtuality tradition's bonus jobs now correctly scale per district rather than applying a flat bonus per planet.
• The Modularity tradition's soldier stability bonus now correctly provides +0.25 stability per 100 soldiers rather than a flat +5.
• The Lathe Cogitator building no longer provides its bonuses when deactivated.
• The Adaptability tradition finisher tooltip now correctly states its bonus applies to all colony types, not just regular planets.
• Tankbound empires with the Void Dwellers origin now correctly receive reduced starting pops and properly converted habitat districts.
• The Machine Fallen Empire's Administration Hub II now correctly provides 1200 unity jobs instead of 600.
• The Living Metal deficit tooltip now correctly states that a shortage reduces Job Output by -30%.
• The Evolutionary Predator hive authority’s reduction to empire size per species trait now functions as expected.
• The Grand Archive event that culls pops now correctly removes 20% of the affected pop group rather than a flat 20 pops.
• The Open Shroud Rift planetary decision can no longer be exploited by queueing it and then terraforming the planet to bypass its planet type restrictions.

Stability

• Fix to an OOS (CS_COUNTRY_AI). 
• Fix to an OOS (COUNTRY_RESOURCES).
• Fixes an OOS caused by the strategic war data being calculated differently on the host and on the clients. 

---

4.3.4 (2026-04-16)

4.3.4 ‘Cetus’ Release Notes

Balance

• Added a cap of 10 years (in defines) for how long a fleet can go MIA. (Exceptions: Phased or Eaten fleets, and those exploring Astral Rifts.)
• Disruptor weapons now also reduce Regeneration Effectiveness on hit for 10 days. 
  • T1: -20% Shield, -10% Armor/Hull Regen. 
  • T2: -35% Shield, -20% Armor/Hull Regen. 
  • T3: -50% Shield, -30% Armor/Hull Regen. 
  • Psionic: -35% Shield Regen, -20% Fire Rate, but remains on the anti-fire-rate channel so will stack with other disruptors.
• Increased Exotic Gas production of Advanced Bio-Reactor to 0.1 from 0.05.
• Increased Ministry of Production and Production Center Alloy and Consumer Goods bonus to 0.2 from 0.1.
• Faculty of Archaeostudies:
  • Biologists on a Relic World now produce +0.25 Minor Artifacts (was +0.1).
  • Archaeo-Engineering AP now increases Biologist Minor Artifact Production by +0.15 (was +0.05).
  • Increased Minor Artifact storage cap to 2000 (was 1000) and the Archaeo-Engineering bonus to 3000 (was 2000).
  • Reduced Building Upkeep to 8 Energy from 10 Energy.
  • Corrected tooltip that has been very wrong for a very long time.
• Astral Siphon:
  • Increased Astral Siphon thread production to +0.2, +0.35, and +0.50 (was +0.1, +0.2, +0.3).
  • Reduced Astral Siphon Physics bonus to +0.2, +0.35, and +0.50 (was +0.25/+0.5/+0.75).
  • Reduced additional upkeep to +1/+1.5/+2 CG or +2/+3/+4 E/M for Gestalts. (Was +1/+2/+4, +2/+4/+8, and +2.5/+5/+10).
  • Increased thread storage to +200, +400, +600 (was +100, +200, +300).
• Reduced the fleet power of Voidworms to be more accurate to their capabilities. (Especially if you use Point Defense against them.)
• High tier habitat capitals can now gain +1 habitat district per major body. Corrected tooltips.

Bugfix

• Fixed Mutagenic Habitability being capped at lower threshold than stated.
• Fixed an issue in the create_random_fleet and create_fleet_from_naval_cap effects that didn't recognize that ships are much bigger than they used to be, so was typically creating fleets five times the size it was supposed to. 
  • This will primarily impact the GDF reinforcement fleet, Revolts, Machine Uprisings, and Civil Wars, Habinte, and a Zevox ending. 
  • The Doom of the Eater fleet has been increased to compensate for this change - plus a little extra on top.
• Fixed the "Volcanic Forge" technology from "Planet Forgers" not appearing for certain origins.
• Adjusted the name of the "Conduit" ship class in the German translation.
• Purges like the Prethoryn, Sentinels, and others now really only occur while they are left alone on the planet. ALL purges now pause any time there is a ground battle for the planet going on. (This includes normal purges, though collateral damage may still kill pops.) 
  • Updated Mechanocalibrator, Terraforming Mutants, Mutant Horrors, and Titanic Guardian events to clean up properly as well.
  • Corrected a logical error where if an empire was bad at purging, they’d be able to slow the decline of pops by setting them as Undesirable.
• Updated Luminary tooltip to reflect their improved lifespan.
• Scourge Missiles were missed in the initial pass that kept torpedoes and similar weapons from dealing 5x intended damage. Your behemoths are now slightly safer.
• Oppressive Autocracies can now build medical centers. 
  • Reminder: Only Elite stratum jobs generate amenities in Oppressive Autocracies and Medical Workers & Genomic Researchers are Specialists.
• Fixed Necrophage+Planet Forgers pre-FTL worlds becoming volcanic at game start.
• Fixed Necrophage+Planet Forgers not getting Volcanic Forge as guaranteed research.
• Fixed Ministry of Acquisition tooltip showing blank consumer goods job name.
• Fixed star_eater_cap displaying as raw LOC key instead of ship name.
• Fixed Offworld Foundry job localization tooltip.
• Corrected Ion Cannon collateral damage. (Should be 100, was 20).
• Storm Chasers should have an increased chance to draw Storm techs, not decreased.
• Fixed tooltips for the Esteemed Quartermaster.
• Sanctuary of Toil tooltip numbers are no longer truncated.
• Increased the width of the Naval Capacity entry on the top bar so the entry in Chinese isn't truncated once you reach XXXX / YYYY Naval Capacity.
• Fixed a logical error that made the Prethoryn Scourge have more fleets on lower difficulties than higher ones.
• Updated Gravity Storms to have a reduced damage penalty based on ship size, since ships are on average 5x larger than they used to be.

AI

• Updated AI alloy and food budgets to better handle new Starbase costs.
• Adjusted AI food budget so bio-ship empires will rebuild their fleets if they recently lost a war.
• Adjusted AI influence budgets so they'll be less prone to immediately allocate their entire influence stockpile to changing vassalization contract terms if they become an Overlord.

Stability

• Fixes an OOS when a hotjoiner is accepted during a hotjoin, after the "start" button had become active in the hotjoin status window.
• Fixed an OOS when a player leaves and rejoins.
• Fixed an OOS related to Spy Networks.
• Fixed an OOS at start when players don't have the same DLC as the host, and someone choses a random empire.
• Fixed issue with particle system crashing due to invalid scripting or very low frame time.
• Fixed issues with fleet move vector distances sometimes end up "freezing" the game.

---

4.3.3 (2026-03-31)

4.3.3 ‘Cetus’ Release Notes

Improvement

• Added Naval Capacity and Command Limit sliders to Advanced Galaxy Settings.
• These range from x0.5 to x5.0 and are multiplicative with all other modifiers in the game. (Warning: Increasing Naval Capacity will have late-game performance and balance implications. Changing Command Limit will have balance implications.)
• The Naval Capacity slider does not change the Naval Capacity hard cap of 9999 or Command Limit hard cap of 1000.

Balance

• Increased the bonus on a number of buildings that provided 5% efficiency bonuses to 10%.

  • These are massive buffs and may require additional balancing if we overshot the mark, considering Space Fauna gain additional bonuses from rarity.
  • Removed some mutations from Frenzied Voidworms (on all difficulties) due to these changes.

Bugfix

• Planetary Automation should now reliably work. (If it's not doing anything, it's often due to the Prevent Deficit Construction setting.)

• Guardian Matrix now also receives the Colony Empire Size penalty reduction all other Sovereign Guardian civics got in 4.3.2.
• Crime Automation now increases jobs 10 at a time (or reduces them 1 at a time) to hit the "sweet spot" faster to better avoid crime events.
• Tier 0 shields no longer grant an army bonus. That's only intended for techs you actually research.
• Sapient, Autonomous, and Precognitive Siege Computers now both have +80% Damage vs. Starbases and Bombardment Damage. (Precognitive Siege Computers retain their Tracking bonus, the other two retain their Evasion bonus.)
• Non-Gestalts on Shattered Rings now have access to the Generator World colony designation
• Fixed starbase hull/armor regeneration bonus applying incorrectly.
• Resolved an issue causing nested tooltips not to stick
• Voidworms will now eventually stop bombarding a planet. Previously, if they could not find a good route home, they’d abort that order, see this delicious planet right next to them, and go for another round.
  • Voidworms will use Experimental Subspace Navigation to get home if absolutely necessary.

AI

• Fixed the AI's tendency to send fleets into much stronger forces.
• Edited AI economic plans and budgets to work better with the 4.3 ruleset.
• Improved AI weighting and decision-making around Urban Districts.
• AI now realizes that Wilderness Harmonic Cores and Singing Cliffs produce Unity, Moltguts produce Alloys, and Threadways produce Trade.
• The AI will no longer infinitely build three Strongholds on a planet, only to immediately destroy them and start building them again.
• Fixed an issue where ships using the Swarm or Siege combat computers would repeatedly break off their attack runs and return to fleet formation when engaging enemies with significantly longer weapon ranges. Swarm and Siege ships now correctly pursue and maintain close-range combat even when the enemy fleet is maneuvering at long range.
• Ships actively engaged with an enemy vessel no longer disengage simply because the enemy fleet flagship has repositioned during the fight. A ship will now only break off its attack if it has drifted far from the specific target it is engaging, rather than reacting to unrelated fleet-level movement elsewhere in the battle.

Stability

• Fixed more rare threading issue with modifier names using wrong memory model for synchronization in threaded context.
• Fixed an OOS between win and non-win machine when using a picket computer during a fight
• Fixed division by zero in particle system propagating NaN down the system and then exploded in CTD
• Fixed faulty logging of invalid/corrupted assets causing stack error resulting in CTD.

4.3.0 (2026-03-17)

4.3.0 ‘Cetus’ Release Notes

The 4.3.0  'Cetus' update focuses on economic balance and performance. Significant changes have been made to the economy to rebalance it at a generally lower power level, with fewer bonuses or modifiers that stack non-linearly to extreme levels. Some traits, buildings, or district specializations may have changed or even been removed. Certain challenges that have been trivialized over the years may be much stronger, especially roaming space fauna, crises, and fallen empires.

Navies have received major changes intended to reduce their total ship counts, making each ship individually more valuable and, we feel, more interesting. Ship defenses have been improved (especially for larger hulls), so combats may last longer than before. Be aware that the Perdition Beams on Titans now deal collateral damage to nearby ships!

Behind the scenes the Custodian programmers focused heavily on performance and stability. You should find the game significantly faster and more stable from the very start until the end-game.

Thank you for playing Stellaris! 
(And additional thanks to the many players that helped us and provided feedback during the 'Cetus' Open Beta!)

Improvement 

• Added the possibility to hotjoin while other players are hotjoining.
• Added Refugee Attraction mechanics:
  • Refactored how Refugees are calculated, they are now more likely to flee to countries ruled by their own species if available and they will pick planets in a smarter manner.
  • Added Refugee Attraction, now Civics like Free Haven will make more refugees show up, while allowing Slavery will reduce the likelihood that people will seek refuge in your empire.
• After a review of Unemployment mechanics, we felt that they did not add significantly to the game.
  • All unemployed pops now demote to Civilian (or Maintenance Drone, as appropriate) at the end of the month.
  • Removed the "Rising Unemployment" event chain.
  • Living Standards have been adjusted.
    • All living standards now include information for Slaves, just in case you find some way to get them unusual and unexpected standards like Utopian Abundance.
    • Happiness penalties on lower living standards now apply to Civilians.
  • Removed Demotion Time bonuses as they’re no longer relevant.
  • Resettlement costs are now the same across all strata. (Since demotion is now immediate at the end of the month, this prevents an undesired element of micromanagement where you would want to fire any pops you wanted to resettle.)
• Improved grammar for French, German, and Spanish translations of empire names for certain randomized empires.
• Reverted the materialist empire being forced to use Cybernetic portraits if you own The Machine Age
• Renamed Mercantile and Unyielding traditions to Commerce and Fortification to match the naming structure of all other traditions.
• Job automation is now moved from district to planet. This means that “Technician Automation” will apply to all technician jobs on a planet instead of only jobs granted from the Generator District.
• Field Modulation, Eco Simulation, and Geothermal Fracking technologies are now marked as Gateway technologies for Rural District Specialization.
• Improvement "Scorched World Heralds" civics now mention that diplomacy with other Thermophiles is possible
• Option text for Rogue Servitors discovering alien life is tonally appropriate
• First Robot timeline event blocked for machine species
• When multiple End Game Crises are active in galaxy settings, End Game Crises are now allowed to spawn 25 years after another crisis has spawned instead of being blocked while there is an active crisis.

    • Note that since player power has decreased by a larger percentage, this will make these Crises a much greater challenge than pre-4.3.
  • Increased many sources of Command Limit and Naval Capacity.
    • Galactic Force Projection, War Games (Supremacy Traditions), and Better Glandular Stimulation (Behemoth Fury Crisis Perk) now grant Command Limit multipliers instead of flat values.

  • Many buildings and modifiers that increased job output have been reduced.
  • Most stability bonuses have been reduced to one half to one third of their previous values.

  • Only the Board of Psychics advanced authority gains +2% Aura Effectiveness.
  • Base income of 5 unity (was 10 energy).

  • Hidden modifier: Increases the chance the AI empires which host the building to take Psionic Ascension by +10% per building.
  • Empathic Marketers are jobs that count as Traders for most purposes, but provide less Trade output in exchange for increasing the chance to draw psionic technologies. They also produce a small additional amount of unity if the host empire has undergone psionic ascension.
• Technocracy changes:
  • Technocracy now provides +1 Scientist Cap, but -1 Official Cap and explains that the additional starting Scientist is the governor of your homeworld.

4.1.0 (2025-09-22)

Shadows of the Shroud DLC

The ‘Arc of Ascension’ is complete at last with Shadows of the Shroud.

• Overhauled Psionic Ascension
  • Like the other Ascension Paths, Psionic Ascension has now been elevated with an Ascension Situation that explores the impact Ascension has on your Empire. Your moral and ethical decisions will influence your attunement to the domains of the Shroud, culminating in your first delve as you Breach the Shroud.
  • Track your exploration of the Shroud in the new Shroud Panel, which will show your current attunement to the domains of the Shroud and provide means to influence your spiritual travels. Attuning to a domain grants Accords, and the local Patron may offer you a Covenant: Power for a price.
  • The Shroud contains 4 Major Patrons, 8 Minor Patrons, and 2 Great Patrons, though not all can be encountered in a single playthrough.
  • Encounter new events when "Delving" into the Shroud, including 4 new Psionic technologies for ship components.
  • A new path through the Shroud where you reject Covenants to forge your own way, beholden to no Patron.
  • An overhauled End of the Cycle
• Psionic Auras
  • The power of the Shroud can influence corporeal reality through Psionic Auras. These manifestations of the strength of your attuned domain or Patron spread outward from your colonies but can be countered by the Shroud Seals of the Mindwarden Enclave.
• 3 New Origins
  • Shroud-Forged: The guidance of a Shroud entity comes with a cost. The entity known as the Animator of Clay has taken a special interest in this Machine Intelligence civilization.
  • Mindwardens: Freedom is meaningless without sovereignty of thought. Carry on the fight of your ancestors by defending the galaxy from psionic threats.
  • Endbringers: IT IS NOT YET YOUR TIME. BUT IT COULD BE.

• Idle gestalt drones now demote much faster.
• Colony Auto-Designation no longer thinks that job producing buildings like Temples are 100x as awesome as it should consider them.

• Added the inner_radius trigger to determine the size of the gravity well of a solar system
• count_species_traits trigger now only filters by category when one is passed as a parameter
• Since we built the citadel anywhere, we needed a way to set its position. The easiest way was to do it in code, so now when you've set a starbase in your megastructure, the code will generate it automatically. However the megastructure will not be destroyed by code, so if you want to do that you still need to do it manually.
• build_outside_gravity_well flag in megastructures is deprecated, replaced with build_type = inside_gravity_well/outside_gravity_well/around_planet used to determine where and how to place a megastructure

• Updated thrusters, FTL Drives, Cloaking Devices, Ship Reactors, Combat Computers and probably more to use scripted triggers

• Added Planet as a possible scope for the has_deficit trigger
• Added the "damage_army" effect
• You can now restrict civics and origins by graphical cultures by using the "graphical_culture = { <restriction> }" restriction in possible or potential. It works like every other civics/origins restriction.
• Added "add_random_species_trait" to modify_species, which takes a trigger that's applied to all the possible species traits, and randomly adds one that fulfills the trigger.
• Added definition for invisible extra large turret
• Added a country_uses_bio_ships scripted trigger
• Technology Swap can now change the Area and Categories of the tech. For example, Corvettes (engineering, voidcraft), can become Brawlers (Society, Biology).

• Added planet_building_capacity_add, allowing planets to function like starbases producing multiple things at the same time
• Static Modifier Custom Tooltips can now have parts of their localization designated to be multiplied when a static modifier is applied. This allows for modifiers such as defensive_stations_tracking_add to be defined entirely in script
• Origins can now be given a room and city_graphical_culture argument to automatically change the players designs when the origin is selected. The AI should respect this too.
• The resources that appear in the top bar are now scriptable and conditional. See how Wilderness handles the Consumer Goods/Biomass swap as an example

• Meet Galactic Heroes: Attract paragons of renown to your council: unique leaders with their own art, events, and stories may join your empire and bring their own benefits to your government. Or, discover four Legendary Paragons with intricate event chains and unique mechanics!

  4. Hundreds of new Leader Traits
  5. Two new Tradition Trees, giving players new edicts and improved leaders
  6. New ships, art, and story content
• 6 new achievements introduced

VERSION 3.8.1 - Gemini

FEATURES

• Added two Cooperative modes, allowing up to five players per empire. More information can be found in Stellaris Dev Diary #293.
  1. Cooperative PvE can be initiated from the main menu - all players that hotjoin the hosted game will join the primary player’s empire. This mode is primarily intended for teaching new players or for lower intensity cooperative gameplay.
  2. Cooperative PvP can be allowed by the host of a standard multiplayer game. When enabled, empires can open themselves up to allow other players to help control their empire. We expect this game mode to be useful for competitive team play.

Please note that Cooperative modes are still considered to be a beta, and may be less stable than standard multiplayer, or may have some unusual experiences. We will continue to polish and refine Cooperative mode over the next few patches.

• Empire Council: Ruling a Galactic Empire is hard work, and your council of trusty leaders is there to help you. Base-game Stellaris now includes a ruling council, where up to three leaders will assist you in ruling your empire - your Ruler, your Head of Research, and your Defense Minister.

  1. Each leader gives bonuses to their area of expertise, which grow increasingly more powerful as they level up over time.
  2. Gestalts will have a collection of immortal “nodes”, that will level up and gain new traits over time, which we feel better suits them thematically.

• Ruler Creator: Added a new step in Empire Creation that permits the selection of your ruler’s appearance and starting trait(s).

• Renowned Leaders: Updated several leaders to use new Leader systems:

  1. Updated Tuborek with new effects to use the Paragon System.
  2. Updated Reth Unddol with new visuals and effects to use the Paragon System.
  3. Updated Gray's Menu and effects to use Paragon Systems.
  4. Updated the Caretaker with new visuals and effects to use the Paragon System.
  5. Updated the S875.1 Warform with new visuals and effects to use the Paragon System.
  6. Updated the Oracle with new visuals and effects to use the Paragon System.

• Ground Combat and Bombardment Changes: Several changes have been made to armies and bombardment.

  1. Army Builder tab added to starbases, which allows easier creation of Assault Armies across a sector.
  2. An army can be set as a Rally Point - new troops will automatically try to merge with this fleet (regardless of whether they were queued with the Army Builder or the old Recruit button).
  3. Planets can now select whether or not to Deploy in Orbit any newly recruited armies.
  4. Planets can now be taken through Orbital Bombardment if all defending troops have been killed. A policy can be set if you wish to refuse this form of surrender, and planets will not surrender to genocidal opponents.
  5. Bombardment is significantly more damaging than it used to be. More pops will die, and more buildings and districts will be ruined.
  6. Orbital Bombardment will now scale with the amount of ships bombarding, the first 100 fleet size ships will do full damage, after that each additional 100 fleet size will add 70% of that efficiency. For example, 300 fleet capacity worth of ships will deal 100% + 70% + (0,7^2 = 49%) = 219% total worth of bombardment damage.
  7. Bombardment effects are scaled based on the number of pops, buildings, and planet size. Small dense planets will suffer greater losses than large, sparsely populated planets.
  8. Ground Combat is also more devastating to planets than it used to be, but much less so than bombarding.
  9. The effect of collateral damage from different army types have also been adjusted, previously the collateral damage on army types was a linear value and not a multiplier, which meant that in practice high damage high collateral units like Xenomorphs could effectively do less collateral damage on the planet compared to normal troops because they would kill the enemy troops very quickly. This is no longer the case as the collateral damage modifier now acts as a multiplier on any damage dealt.
  10. Planetary Capital buildings now spawns 0/4/8/16 defensive armies for free based on the tier of the building.

• Sector Editor: It is now possible to edit Sectors in the Planets and Sectors screen. Systems can be freely moved between sectors as long as they are in range of the Sector Capital. Sector Capitals must now be at least four jumps away from any others.

• Customizable Menu: It is now possible to rearrange the list of options in the left side menu, by pressing the new Cog icon at the top. This will also correspondingly change the hotkeys to open these menus, allowing you to rebind these menu items to whichever F1-F10 key you prefer to have them on.

• Customizable Message Notifications and Toasts: Messages and notifications can now be customized to suit your needs.

  1. Added a new message type called a “toast”, which pops up and disappears automatically after a brief period of time.
  2. Settings -> Messages, Ctrl+Click, or cogs (on certain messages) will open the Message Settings menu.
  3. Messages can be disabled, enabled, or set to automatically pause the game.

• Fleet and Ship Designer:

  1. Merged into tabs of the same screen.
  2. Now displays a longer list of fleets.
  3. Copy Fleet Template and Overwrite Fleet Template features added.
  4. Delete + Enter will delete a fleet.

  1. Explore Systems - will explore the galaxy by entering systems and discover any planets and hyperlanes in there
